Question

Peter is twice as old as paul was when peter was as old as paul is now. the combined age of peter and paul is 42 years. how old is peter now?

Answer 1

Let the age of Paul be 'x' years.

Since, Peter is twice as old as Paul.

Therefore, Peter's age = $2 \times x$ = 2x years.

Since, the combined age of peter and paul is 42 years.

Therefore, x+ 2x = 42

3x = 42

x = 13

So, Paul's age is 13 years.

Peter's age = $2 \times 13$ = 26 years.

Therefore, Peter is 26 years old.

Answer 2

Answer:

Step-by-step explanation:

Let the age of Paul be 'x' years.

Since, Peter is twice as old as Paul.

Therefore, Peter's age = 2x years.

Since, the combined age of peter and paul is 42 years.

Therefore, x+ 2x = 42

3x = 42

x = 13

So, Paul's age is 13 years.

Peter's age =  = 26 years.

Therefore, Peter is 26 years old.
